Comparison of twin pregnancy outcome after assisted reproductive technology with and without embryo reduction

Background: Spontaneous occurrences of multifetal pregnancies always have been a medical problem. The risks of perinatal morbidity and mortality and maternal morbidity increase with enhancement of the number of fetuses. In our prospective experimental study, the outcome of twin pregnancy after Assisted Reproductive Technologies (ART) with and without Multifetal Pregnancy Reduction (MFPR) is com...

Assisted reproductive technology and pregnancy outcome.

OBJECTIVE To determine whether the use of assisted reproductive technology (ART) is associated with an increase in chromosomal abnormalities, fetal malformations, or adverse pregnancy outcomes. METHODS A prospective database from a large multicenter investigation of singleton pregnancies, the First And Second Trimester Evaluation of Risk trial, was examined. Subjects were divided into 3 group...

The Comparison Between the Pregnancy Outcome after Easy Embryo Transfer and Difficult Embryo Transfer

Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two ET types. Methods: This study was performed retrospectively on 295 infertile patien...

The Effect of Intercourse around Embryo Transfer on Pregnancy Rate in Assisted Reproductive Technology Cycles

Background Implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) failure. Several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. This study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patients...

Heterotopic Pregnancy after Assisted Reproductive Techniques

Heterotopic pregnancy (HP) is the simultaneous occurrence of intra- and extrauterine pregnancies. It is a rare event in spontaneous pregnancies with an incidence of less than 1:15000 however the frequency has increased to 1% in accordance with the widespread use of assisted reproductive techniques (ART). The pre-operative diagnosis of this condition is generally difficult and it would be life t...
